refactor: update cursor styles and progress variable

- Removed cursor pointer from .art-mask-show in mask.less for better UX.
- Added cursor pointer to .art-progress in progress.less to indicate interactivity.
- Adjusted hover effect for .art-control-progress-inner in progress.less to enhance visual feedback.
- Increased --art-progress-top-gap variable from 8px to 10px in variables.less for improved layout.
- Removed cursor pointer from .art-video in video.less to streamline styling.
